STK0060 60W

STK0060 60W
Features of STK0060:
General output stage of power amplifier has a difficult and complex problem about heat sink designing and its settings. Sanyo's DP intends to decrease electronic parts and rationalize a manufacturing process by designing IC of only output stage pf power amplifier.

  • IMST Systems
  • Output stage for AF high power amplifier.
  • Dual power supply
  • Darlington type pure/ quasi-complementary circuit
  • These same pin assignment and pin interval lead to standardize a printed board.
  • Metal substrate use IMST makes good thermal stability
  • Able to design freely previous section of power amplifier. This leads tone control designing.
Equivalent Circuit.
